Coffee is one of the most popular drinks in the world, and coffee beans are an important raw material for making coffee. There are many different varieties of coffee beans around the world. However, there are three main varieties that are widely recognized and used. They are Arabica, Robusta, and Liberica.
First of all, Arabica is recognized as one of the high-quality coffee beans. This variety originated in Ethiopia and is widely cultivated around the world. Arabica beans generally have lower acidity and bitterness, with rich floral and fruity flavors. They also contain less caffeine, making them smoother to drink.
Secondly, Robusta is another common and widely used variety of coffee beans. Compared with Arabica, Robusta is easier to grow and adapt to various climate conditions, and is especially popular in low-altitude areas. These beans usually have higher acidity, bitterness, and a strong taste, and contain higher caffeine content. Robusta beans are also often used to make strong espresso.
Finally, Liberica is a relatively rare but unique coffee bean variety. It originated in West Africa and is widely cultivated in some parts of Asia. Liberica beans usually have a unique and strong taste, with woody or fruity aromas and low acidity. This variety is highly adaptable and has low climate and soil requirements.
